It really does come down to personal preferences and what your workflow is like. I use a little bit of everything to model. It all depends on what I'm trying to accomplish. mostly use Hexagon, the only down side to it is if you have an n-gon, it will crash if you saved it with the n-gon. Previous statement is based on my personal observations. Sometimes I use Carrara 7 pro, been playing with Sculptris (not very good at it though-lol). Can't wrap my head around some of the free options out there. I absolutely love Marvelous Designer for clothing but sadly, it's not in my price range at the moment.

chaecuna has made some pretty good points about the various software mentioned. What I would do is to download the free trials, most software has a limited time or function trial. See which you like that's in your price range and has a comfortable workflow for you.

Have a creative day!
